Perhaps you should try some spelling variations:
"post optimisation algorithm" » "post optimization algorithms", "post estimation algorithm", "robust optimization algorithm", "_ optimisation algorithm", "qoe optimization algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ approximation algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("post optimisation algorithm") or ("_ estimation algorithms"))) or ("_ optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("post optimisation algorithm") OR ("_ estimation algorithms"))) OR ("_ optimized algorithm"))*.
• Removing quotes may allow a broader search: (((( post optimisation algorithm ) or ( _ estimation algorithms ))) or ( _ optimized algorithm ))*.
